I BOTTLE.

T0 at whom it may concern.-

Be it known that I, ARTHUR BYERS ADAIIt, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented a new and useful Bottle, of which the following isaspecification.

This invention relates to improvements in bottles, and has for itsobject to provide a simply-constructed device of this class from whichthe contents cannot be removed and the bottle refilled withoutdetection.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the invention consists. in certainnovel features of construction, as hereinafter fully described andchanges in the form, proportion, and minor details of construction maybe resorted to without departing from the principle or sacrificing anyof the advantages of this insame.

vention within the scope of the appended claim.

In the drawings, Figure 1 is a sectional view of the neck portion of abottle embodying the improvements with the stopper and plug removed, andFig. 2 is a plan view of the Fig. 3 is a view similar to Fig. 1 with thestopper and plug in position in the neck of the bottle. Fig. 4 is aperspective view of the plug detached.

The body of the bottle is indicated at 10 and the neck at 11, the latteradapted to receive a stopper 12, of cork or the like, in the portionnext the body of the bottle.

Surrounding the neck 11 is a breakinggroove 13, and formed in theinterior of the neck is a recess 14, preferably annular in form and withits lower end 15 in transverse I alinement with the groove 13, so thatwhen Specification of Letters Patent. Application filed June 25, 1906.Serial No. 323,369.

more internal recesses 16, preferably segmental in form.

Engaging the neck 11 between the recess 14 and the outer terminal of theneck 11 is a plug 17 having a reduced lower portion 18, having anenlarged terminal 19, the reduced portion and its enlarged end extendinginto the space opposite the recess 14. At its outer end the plug 17 isformed with a lateral flange 20, bearing over the outer terminal of theneck, and with lateral projections 21 for engaging the recesses 16. Theplug 17, together with its reduced portion 18 19, and the flange 20 andprojections 21 are of glass or like material, preferably of the samequality as the body and neck of the bottle.

After the bottle has been filled the stopper 12 is inserted and plasticmaterial or compound (indicated. at 22) is inserted above the stopperand nearly filling the recess 14. The plug is then inserted before theplastic material hardens, the reduced portion 18 19 displacing a portionof the same and forcing it into the recess 14 and around the enlargedterminal 19. The plug is forced into the neck 11 until the projections21 enter the recesses 16 and the flange 20 bears upon the end of theneck, as shown in Fig. 3.

When the plastic material hardens, it will i be obvious that the plugcannot be detached without fracturing the neck or the plug, and as theprojections 21 by engaging the recesses 16 effectually prevent rotarymotion to the plug the hardened plastic material cannot be loosened orfractured by that means. The

plastic material may be of any suitable quality, but will preferably beof plaster-of-paris or similar material.

When access to the contents of the bottle is desired, alaterally-imparted blow to the portion of the neck in advance of thegroove will fracture the neck at the groove, and by reason of the innerend 15 of the recess 14 being disposed in transverse alinement with thegroove a relatively smooth even fracture will be produced without jaggedportions. This is an important feature of the invention and addsmateriallyto the value and efficiency of the device.

. The removal of the outer portion of the .neck, together with its plugand the hardened plastic material, exposes the outer end'of the stopper12, which may be readily removed by a corkscrew or other implement. Bythis means the contents of the bottle are effectually protected andaccess thereto cannot be obtained or the bottle employed the second timewithout detection.

Having thus described the invention, what is claimed is A bottle theneck whereof is adapted to receive a stopper and provided with internalcavities at its outer terminal and an external breaking-groove inadvance of the stopper- I'eceiving portion and an internal recessbetween the groove and the outer terminal of the neck, a plug engagingthe neck between the recess and the outer terminal of the neck ARTHURBYERS ADAIR.
